## Testing Patterns Used

### 1. Arrange-Act-Assert (AAA)
All tests follow the AAA pattern for clarity:
```python
def test_example():
    # Arrange - Set up test data
    player = create_test_character(age_years=25)

    # Act - Execute the function
    score = calculate_compatibility(player, match)

    # Assert - Verify results
    assert score > 60
```

### 2. Mock Strategy
- Database connections mocked with MagicMock
- OpenAI API calls mocked for deterministic testing
- External dependencies isolated

### 3. Edge Case Coverage
- Empty/missing data handling
- Boundary conditions (0-100 scores)
- Error scenarios (person not found, invalid activity)
- Zero/null values handling

### 4. Clear Documentation
Every test includes:
- Descriptive test name
- Docstring with ARRANGE-ACT-ASSERT breakdown
- Clear assertions with comments

- Test data is generated programmatically, not from static fixtures
- All edge cases and error conditions are tested
- Tests are deterministic and reproducible
